DISK-CUTTING MACHINE.

Specification of Letters Patent. I Patented B131. 14, 1916.

Application filed December 15, 1914. Serial No. 877,412.

1 '0 all whom it may concern Be it known that I, ALEXANDER Booiniivrrr, a subject of the King of Hungary,

and a resident of the city of New York, in the county of Kings and State of New York, have invented certain new and usefullme 'provements in Disk-Cutting Machines, of

which the following is a specification.

The present invention relates to improvements in machines for cutting cork or similar disks for use in closures, such as for in stance crown corks. I

The invention pertains more particularly to a machine for cutting a cylinder or rod of cork or similar material into disks of a predetermined thickness.

wherein a single knife is used in conjunction with aplurality of cork holding magazines, in combination with a slmple and positive feeding mechanism.

A still further object of the invention is to so arrange the elements of the machine to permit the thickness of the disks to be cut to be varied according to the requirements.

lVith these and other objects in view, which will more fully appear as the nature of the invention is better understood, thesame consists in the combination, arrange ment and construction of parts hereinafter fully described, pointed out inthe appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and pro-,

portion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

One of the many possible embodiments of the invention 18 illustrated 1n the accompanying draw ngs, in wh1ch:'

Figure 1 is a front elevation of a machine constructed in accordance with the present invention; Fig. 2 is a side elevation thereof;

Fig. 3 is a plan view of the same; Fig. 4 is a plan view of a portion of the machine on a larger scale, partly in section; Fig. 5 is a plan view of aportion of-the work table and the feeding mechanism, partly in sec-' tion; Fig. 6 is a section taken on line 6-6 of Fig. 5; Fig. 7 1s a section taken on line -(7 of Fig. 5; Fig. 7 is a perspective view,

partly in section, of a portion of the detail shown in Fig. 7; and Fig. 8 is a side elevation of a detail of construction.

Before going into the details of the machine, attention is called to the fact that,

although in the drawings there have been shown two machines combined into one, that is to say two work supporting tables with two knives, it is obvious that the same could be built as a single machine, that is consistng of one work supporting table cooperatlng with one knife only.

Referring now to the drawings, the numeral 10 indicates the frame of the machine, including a horizontally disposed bed plate 11 on each. side thereof. In each bed plate are formed two longitudinally extending parallel guideways 12, in which are seated rails 13, which are formed upon the underfaces of work tables 14, there being one table disposed on each bed plate. The tables may be reciprocated upon the bed plates inany suitable manner, for instance the tables are each provided with a downwardly extending vertical plate member 15, which is rigidly attached thereto and provided each with a vertical slot 16. In each slot is slidably disposed a block 17, said blocks being'formed upon crank disks 18, the latter being keyed or otherwise fixedly attached to the main driving shaft 19 of the machine, said driving shaft being rotatably mounted in bearings 20, which are formed upon the frame 10. Rotation is imparted to the driving shaft from any suitable source of power by a belt 21, that runs over a driving pulley 22, which is keyed to said shaft. T he crank disks are keved to the driving shaft in such a'manner that, in the rotation of the latter, the work tables reciprocate always in opposite directions.

Upon each of the tables are disposed a plurality of rod holding magazines. For this purpose there are formed in the upper faces of the tables grooves 23, the bottoms of which are substantially semi-cylindrical. These grooves run throughout the widths of the tables in parallel relation to the main driving shaft. On each table these grooves are divided into two groups, one group, denoted by the numeral 24, being arranged near one end of the table, and the other group, designated by the numeral 25, near the other end thereof. The purpose of this arrangement is, as will hereinafter appear, to make each table double acting, that is to say to run the machine without idle strokes.

Along the inner edge of each table is formed a longitudinal ledge 26, in which are formed cylindrical bores 27 in alinement with and forming a continuation of the grooves 23. Each bore 27 is provided with an enlargement 28 for a purpose presently to be described. Ineach bore is slidably disposed a feeding finger 29 in the form of a spring collet, that is provided, besides the usual longitudinal slots 30, at its upper portion with a wider longitudinal slot 31, and in alinement with thelatter' at its lower portion with a similar slot 32. Into the slots 32 project strips 33, which are fixedly attached to the table, such strips'serving, besides a purpose hereinafter to be described, to prevent a rotary motion of the feeding fingers in relation to the tables; The inner table.

ends of the feeding fingers are somewhat thickened, as clearly shown at 34, these thickened portions being disposed in the enlarged sections of the bores, and each of the same being provided with an upwardly proparallel axes of the two groups of slots converging toward the transverse center line of each table, or in other words the two groups of'slots are inclined in opposite di-' rections. With each actuating bar 37 cooperate two stops 39, oneon each end ofthe bed plate 11. These stops comprise, for instance, each a standard 40, that is suitably fastenedto the bed plate, and a horizontally disposed set screw 41 in the path of the bar 37. By adjusting the positions of the. set screws 41, obviously the strokes of the bars 37 and thus the "extent of the feed may be varied, as will hereinafter appear.

With each feeding finger cooperates a gripping jaw 42. These jaws are 'slidably disposed in pockets 43, formed in the ledges 26 on the tables. The jaws are provided with teeth 44 on their underfaces, said teeth projecting through the slots 31. These jaws cooperatewith the strips 33, which are, as above described, seated in the slots 32 in the feeding fingers. Each gripping jaw is provided with a recess '45, in which is seated an eccentric 46, that is either made integral with or suitably attached to a rocking shaft.

I tables.

47. There is one shaft 47 associated with each table, the shafts being oscillatably mounted in the ledges 26, and provided'each with a bevel gear 48. The bevel gear 48 of each shaft meshes with a similar gear 49, that is fixedly attached to a shaft 50, the latter being journaled in bearings51 on the The shafts 50 extend at right angles to the shafts 47, and carry at their outer ends each a lever 52. These levers carry each an anti-friction roller 53, said rollers being adapted to cooperate with cams 54.

These cams are attached to the bed plate 11,

one in front of the machine and the other 7 in rear thereof. The cams have each two slanting faces 55 and 56, which converge toward-the center lineof the machine, as clearly shown in Fig. 1 of the drawings. The eccentrics 46 associated with the group 24 of grooves are all alike. and in registerin g positions, and so are also those associated with the group 25 of grooves 23. It is to be noted, however, that the cams associated with the group25 of grooves are staggered in relation to the cams associated with the group 24 of grooves, as appears clearly from Fig. 8 of the drawings With each table cooperates a disk knife 57. These knives are rigidly attached to an arbor 58, that is mounted in bearings 59. Rotationis imparted to this'arbor by a belt 60, that is actuated by any suitable source of power and runs over a pulley 61, keyed to. said arbor. Below each knifeis disposed a chute 62, into which the disks fall, to slide into containers placed b'elow said chutes.

The operation of this machine is as follows: It is necessary to consider the operation of one table. and its appurtenances only, since the other table worksin a similar manner. Let us consider the operation of the table on the left-side of Fig. .3 of the drawings. The cork rods or cylinders 63 are placed into the. grooves 23 manually, andslid in said grooves and feeding fingers until they are broughtwithin the reach of the gripping jaws 42. In the positions of the'parts shown in Figs. 1, 3 and 4 of the drawings, the grooves of the group 24 of the table have already passed the cutting edge of the knife. Immediately before the table reaches this position, the bar 37 is shifted by the corresponding stop 41 in the direction of the arrow shown in Fig. 4 of the drawings, whereby the feeding fingers associated with the group 24 move away from the knife, and the feeding fingers associated with the group 25 of grooves move in the opposite direction, for the reason that the slots 36, which cooperate with the lugs 35 on the feeding fingers, are, as above described, con-V verging toward the transverse center line of thejtable. Before, howeverythe feeding fin-v gers move in the directions indicated, the shaft 47 is given' a rocking motion by the the corresponding gripping jaws, so that their teeth 44: engage with the cork cylinders or rods in said grooves and press them against the strips 33 therein. In other u words, before the feeding fingers move toward the knife; and thereby feed the cork cylinders or rods a predetermined distance, depending upon the stroke of the bar 37', to the knife, the corresponding gripping jaws are raised, and when the feeding fingers move in the opposite direction, the corre sponding gripping jaws are lowered into contact with the rods, so as to prevent them from sliding backward with the backwardly moving fingers. The table moves then in the opposite direction, the knife slicing disks from the rods in the group of grooves. At the same time the anti-friction roller 53 of the lever 52 is lowered and rides near the end of the stroke of the table up the inclined face 55 of the cam 54:, whereby the jaws associated with the group 25 of the grooves are forced into contact with the rods or cylinders therein, and the jaws cooperating with the group 24 of the grooves are raised. Before theend of the stroke is reached, the bar 37 is moved by the corre-' sponding stop 41 in the corresponding direction, moving the feeding fingers associated with the group 25 of grooves away from the knife, and those eoacting with the group 24 of grooves toward the knife, thus feeding the cork cylinders or rods in the manner above described toward the knife. The cycle of operation now described is then repeated.

It is to be observed that neither one of the tables has an idle stroke, the knives cutting at both strokes of the tables.

It should be observed that the inner face of the knife is, preferably, concave to prevent undue friction between the same and the cork cylinders or rods. The feed is entirely automatic. The strokes of the feeding fingers are easily adjusted, as appears from above, and thus the thickness of the cork disks conveniently predetermined.
